Connector With Selective Insulation Ribs for Crosstalk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing input/output connectors face limitations in performance and resonance suppression due to the width and spacing constraints imposed by insulation partition ribs between contacts, which restrict the effective separation of elastic arms and lead to short circuits.
Innovation Solution
A connector design where insulation partition ribs are only disposed between ground contacts and adjacent signal contacts, eliminating ribs between adjacent signal contacts to allow for increased spacing and reduced resonance, while maintaining separation between ground and signal contacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insulation partition ribs are disposed between all adjacent contacts, then short circuit between elastic arms is prevented, but the width of contacts and spacing between adjacent contacts is limited
Solution Approach 1:
The patent applies local quality by selectively positioning insulation partition ribs only between ground contacts and signal contacts, rather than between all adjacent contacts. This localized approach maintains necessary electrical isolation where needed (between different signal types) while eliminating unnecessary ribs between same-type contacts, thereby increasing spacing and reducing resonance in those specific regions.
2Reliability
If insulation partition ribs are disposed between all adjacent contacts, then electrical isolation is maintained, but resonance suppression is restricted
Solution Approach 1:
The patent implements local quality by creating different structural configurations in different regions: insulation ribs are present between ground and signal contacts for electrical isolation, but absent between adjacent signal contacts to reduce resonance. This localized differentiation allows simultaneous optimization of both electrical isolation and resonance suppression.
Solution Approach 2:
The patent applies the extraction principle by removing insulation partition ribs from specific locations between adjacent signal contacts where they are not needed for electrical isolation. This selective removal eliminates the harmful resonance effect caused by the ribs while maintaining necessary isolation between ground and signal contacts.
3Reliability
If insulation partition ribs are disposed between ground contacts and signal contacts, then far-end crosstalk is reduced, but device complexity increases
Solution Approach 1:
The patent applies local quality by positioning insulation partition ribs specifically at interfaces between ground contacts and signal contacts, where crosstalk prevention is most critical. This selective placement provides effective far-end crosstalk reduction while avoiding the complexity of universal rib placement across all contact pairs.

AI summary
A connector comprises an insulation body having a plurality of first insulation partition ribs and a row of first contacts arranged on the insulation body at a first pitch. The row of first contacts includes a plurality of first ground contacts and a plurality of first signal contacts. At least two first signal contacts are disposed between two adjacent first ground contacts. Each of the first ground contacts and each of the first signal contacts has a first contact portion, a first fixation portion, and a first elastic arm between the first contact portion and the first fixation portion. Each first insulation partition rib is disposed between the first elastic arm of each first ground contact and the first elastic arm of one first signal contact adjacent to the first ground contact. No insulation rib is disposed between the first elastic arms of any two adjacent first signal contacts.
